Definition of lattice

Lattice can be purchased pre-made (strips are typically on the diagonal) in sheets that are up to 4' wide by 8' long. It comes in wood, pressure-treated wood, and plastic-that-looks-like-painted wood (in limited colors.)

A caution about the premade wood lattice: it is held together with small brads or staples, which can work loose after a season or two.

Making your own lattice is fairly easy, and you can make it straight up and across instead of diagonal. It requires only a few handtools (saw, tape measure, an accurate square, and screwdriver.)
